--- Quote from: pcprogrammer on August 22, 2022, 08:24:07 am ---Just a thought, no idea if it is possible, but what if we extract CO2 from the atmosphere and recombine it with what ever is needed to make some sort of synthetic gasoline and keep running internal combustion engines on it and call it CO2 neutral. This instead of massively producing batteries for electric vehicles. Does not solve the excessive amount of CO2 there is now, but just switching to "renewable" energy does not solve this either. Only active extraction of CO2 and safely storing it could do it in a short time frame. Still leaves a lot of other problems with other forms of pollution, but something to think about. --- End quote --- Where do you get the energy from to extract the CO2 and convert it back to gasoline? I'm sure you're aware it will take much more energy to do that, then was produced from burning the gasoline. |

Did not really think that through, but the same argument applies to the whole transition to "renewables". It still takes a lot of energy to mine the resources and produce the batteries, solar panels and windmills. Not to mention the energy and effort required to change the whole infrastructure. But as stated before I'm no chemist and have no clue as to what would be needed in a process to convert CO2 into gasoline. Just spitting out thoughts. |

There are already days when the power generation by renewables is more than needed, and the price of electricity goes negative. The more renewables, the more of these days will happen. BTW, carbon capture directly from air, would still be non-profitable for a long time, when you still can place it to the chimney of a coal fired plant. |

Sooner or later, probably later, the entire universe will fall into a black hole. That is, if it isn't there already. And when that black hole goes bang, everything will start over again. And an entirely different race of intelligent beings will argue about energy again. And then, even later still, it will happen all over again. And again! And again! And ............. |

Yes that is something that might happen, and who knows how often it has already happened. But it will probably be long after our civilization went extinct all on its own. Estimates for the sun are about 4 billion years before it runs out and fries all the planets in its vicinity. Human race, who knows, but definitely much sooner than the sun. |
